Misery 2.1.1 - Crash on load still present Thread - MISERY mod for S.T.A.L.K.E.R.: Call of Pripyat

I'm getting this:

FATAL ERROR

[error]Expression : !m_error_code
[error]Function : raii_guard::~raii_guard
[error]File : D:\prog_repository\sources\trunk\xrServerEntities\script_storage.cpp

[error]Description : ...f pripyat - misery\gamedata\scripts\ai_tweaks.script:581: attempt to index field 'actor' (a nil value)

I know it used to be a problem in 2.1 and earlier but I've been many places and can't seem to find anyone having this problem for 2.1.1. Is there a fix I can download for it or am I boned?

Where is this happening and what are you doing at the time? What is your alife.ltx switch_distance?

When I try to load my save, it gets to "Press any key" then crashes. I'm in Jupiter almost ready to go to Pripyat and I haven't had it until now. Switch distance is default.

Does it do it on earlier saves or just the last? Did you kill the mercs on top of the scientist bunker early? If it happens on all saves, try lowering your switch_distance to 50 and moving off 100 meters. Save then try again at 300 (default) switch distance. What is your CPU boost speed?
